VEHICLE-WHEEL.

Specification of Letters Patent.

Patented. May 25, 1915.

Application filed July 6, 1914. Serial No. 849,047.

To all whom it may concern Be it known that I, CHRISTIAN M. PETER- SEN,a citizen of the United States, residing at Seattle, in the county ofKing and State of WVashington, have invented a certain new and usefulImprovement in Vehicle-"Wheels, of which the following is aspecification.

My invention relates to improvements 1n resilient wheels that areparticularly adapted for automobiles, auto-trucks and the like, and theobject of my improvementis to provide wheels of this class which shallbe simple to make, reliable, and durable under all conditions of use andwhich shall be resilient to such degree as will perm't the use of solidcushion tires or iron tires thus to 0bviate the greater cost and theannoyance of frequent puncture of pneumatic tires. Iaccomplish thisobject by devices illustrated in the accompanying drawings whereinFigure 1 illustrates a wheel embody ng one form of my invention by aview in s de elevation, a portion only of one part belng shown, moreclearly to disclose other parts, While a portion of each of three otherparts are shown in vertical section, and Fig. 2 1s a view of the same incross-section on broken line A, A of Fig. 1.

Referring to the drawings, throughout which like reference numeralsindicate like parts, 5 is the rim of a wheel and 6 is a two part solidtire, preferably of the rubber cushion type, that is mounted on the r m5, which rim 5 is preferably formed with a centrally disposed annularridge 7 that projects outwardly therefrom between the two sections ofsaid tire to prevent such sections from moving sidewise on said rim 5.

The outer side edges 8 of the rim 5 are curved downwardly, as moreclearly shown in Fig. 2, and a wheel 9 of any ordinary form ofconstruction is disposed concentrically within the rim 5, the rim 10 ofthe wheel 9 being spaced from the rim 5 and interposed between such tire10 and the rim 5 are a plurality of compression springs 11 which springsare preferably set in alternate angular positions, every alternate oneof such springs 11 being inclined outwardly in one direction to bearagainst the rim near one edge thereof and the remaining springs 11 beinginclined outwardly in the opposite direction to bear against the rim 5near its opposite edge to secure the wheel 9 against sidewisedisplacement with respect "the springs 11 to the rim 5, and further toserve as a cushion between the rim 10 of the wheel 9 and the greater rim5, there being provided in said rim 5 inwardly projecting studs 12 thatserve as guides to secure the outer ends of l in their proper positions,the nner ends of such springs 11 being secured in a fixed position onthe tire 10 by studs 13 provided on the ends of the spokes 14 of thewheel 9.

To insure that the wheel 9 may not be moved sidewise within the rim 5against the pressure of the inclined springs 11 I have provided aplurality of guide studs 15 that be formed integral with the rim 5 orrigidly secured thereto to project inwardly therefrom through slots orholes 16 that are provided in thetire 10 of the wheel 9, as more clearlyshown in Fig. 1.

To prevent the collection of dirt within the wheel 9 and the rim 5 Ihave provided concavo-convex shaped side plates 17 for each side of suchwheel, such plates 17 being provlded near their peripheries withengaging hooks or lugs 18, more clearly shown in Fig. 2, that engagewith the inturned edge portions 8 of the rim 5 to hold the side plates17 in position, the hooks 18 being inserted through notches 19 in suchinturned edges 8 and the plate 17 then being turned through a part of arevolution to cause such hooks 18 to engage securely with the inturnededge portions 8 of the rim 5, there being provided screws 20 that arescrewed through the plates 17 to project through the notches 19 toprevent the plates from turning after they have been secured in place.

The plates 17 are each provided with a large opening 21 that isconcentric with the hub 22 of the wheel 9 within which said hub 22 maybe free to move when the plates 17 are in place, and such plates arepreferably constructed of light thin metal, as of sheet aluminum, andare formed with radial openings 23 that are covered by light thin sheetmaterial 24:, as of sheet metal or canvas.

The peripheral edges of the plates 17 are disposed to project outwardlypast the outer surface of the rim 5 to engage with the sides of thetires 6 to hold such tires 6 in place when said side plates 17 aresecured in their normal positions on the wheel.

The operation of my spring wheel may be described as follows: When thewheel is assembled, as shown in Fig. 2, a motor vehicle, as on anautomobile, the springs 11 on the lower side of such wheel will bebrought under compression and then that part of the weight of thevehicle that is carried by the wheel 9 will be borne by such springs 11in such lower side and if the vehicle is moved over an uneven surface ofa rough roadbed the springs 11, between the rim 5 and the tire 10 of thewheel 9, together with the solid tire 6, will be compressed and serve toabsorb the shock occasioned by the passage of such wheel over such roughsurface. v

Obviously, numerous changes in the form of the various details embodiedin my wheel may be resorted to without departing from the spirit of myinvention or sacrificmg any of its advantages.

and placed on spring round said wheel and spaced therefrom, said outerrim being provided with inturned notched edges, springs interposedbetween said rim and the tire of said wheel, tires provided on saidouter rim, and side plates provided with catch hooks that are adapted toengage with the inner faces of the inturned edges of said outer rim tosecuresaid side plates to said wheel. y

In witness whereof, I hereunto subscribe my name this 20th day of June,A.'D.'1914.
